Our Primordial Need for Blankets
The desire to sleep under blankets, even in sweltering temperatures, is a universal human phenomenon. As I experienced firsthand on a hot summer night in New York City, the need for some form of covering is deeply ingrained. But what drives this compulsion? Historically, blankets were a luxury only the wealthy could afford, with the first linen bedsheets emerging in ancient Egypt around 3500 B.C. The high cost of production made bedding inaccessible to the masses until the Early Modern period in Europe, when increased production and trade made it more widely available.
According to Roger Ekirch, a historian at Virginia Tech, “The bed, throughout Western Europe at this time, was the most expensive item in the house.” The bed and bedding could account for up to a third of the total value of an entire household’s possessions. This highlights the significance of bedding in human history and the depth of our attachment to it.
Despite the abundance of research on human behavior, the study of sleep and bedding remains a relatively unexplored field. A 2002 paper by Carol Worthman and Melissa Melby of Emory University found that, even in hot climates, people use some form of covering to sleep, whether it’s plant matter or woven fabric. This suggests that our need for blankets is not just a cultural phenomenon but a fundamental aspect of human behavior.
The Physiology of Blanket Dependence
From a physiological perspective, our bodies undergo significant changes during sleep, particularly during the REM periods. Our core temperature drops, and we become less able to regulate our own body heat. This is why, even in hot climates, nighttime temperatures can drop significantly, making a blanket necessary for thermoregulation. Dr. Alice Hoagland, director of the insomnia clinic at the Unity Sleep Disorder Center, explains that our bodies revert to a more “reptilian” form of thermoregulation during REM sleep, relying on external means to adjust our temperature.
Additionally, research has shown that weighted blankets can have a calming effect, increasing the production of serotonin in the brain. This suggests that our need for blankets may be linked to a deeper psychological and physiological need for comfort and security. Hoagland notes that our attachment to blankets can be attributed to “pure conditioning,” where our brains associate the feeling of being covered with the process of falling asleep.
The use of blankets also seems to be linked to our brain’s production of melatonin, a hormone that induces sleepiness. Studies have shown that a slight drop in body temperature, achieved through the use of skinsuits, can improve sleep quality. This suggests that our need for blankets may be an evolutionary adaptation to help regulate our body temperature and promote better sleep.
The Winners and Losers of Blanket Dependence
The widespread use of blankets has significant economic and environmental implications. The textile industry, which produces bedding and blankets, is a major contributor to greenhouse gas emissions and waste generation. On the other hand, the demand for blankets has created a lucrative market for manufacturers and retailers.
From a social perspective, the use of blankets has also been linked to cultural and socioeconomic status. In the past, the quality and quantity of bedding were often seen as indicators of wealth and status. Today, the use of blankets continues to be influenced by cultural and social norms, with different societies and communities having their own unique preferences and traditions when it comes to bedding.
The impact of blanket dependence on the environment and human health is a complex issue that requires further research and consideration. As we move forward, it is essential to explore sustainable and eco-friendly alternatives to traditional blankets, as well as to promote healthier sleep habits and practices.
The Skeptical Case
While the evidence suggests that our need for blankets is deeply ingrained, there are also arguments to be made against the universal use of blankets. Some critics argue that the use of blankets can be detrimental to our health, particularly in hot climates, where it can lead to overheating and discomfort. Others argue that the textile industry’s environmental impact outweighs any potential benefits of blanket use.
It is also worth noting that the science behind blanket dependence is not yet fully understood, and more research is needed to fully comprehend the complex physiological and psychological mechanisms at play. As we continue to explore the intricacies of human behavior and sleep, it is essential to approach the topic with a critical and nuanced perspective.
The Signal to Watch Next
As we move forward, it will be essential to monitor the development of sustainable and eco-friendly alternatives to traditional blankets. The rise of innovative materials and technologies, such as temperature-regulating fabrics and smart textiles, may offer new solutions to the environmental and health concerns associated with blanket use.
The next significant event to watch will be the release of new studies and research on the science behind blanket dependence. As our understanding of the complex physiological and psychological mechanisms at play continues to evolve, we may uncover new insights into the universal human phenomenon of blanket use.
